'Indicated' generally at I0', the combined clock and calendar 'device oi my invention, consists of an electric lclock l2 of any conventional and suitabi-e construction 'mounted in the upper portion of a base "M, Whose lower portion housesl the 'calendar' datmn web and its actuating mechanism W, the indicia ofthe web being presented for visual as by a Window f8, in the Afront ofthey case.

Referring'fl'rst to Figure 3', it 'will' "ce seen that an electric clock l2 is provided with an extemal gearv 20, secured to its hour hand shaft, which meshes with a. gear'22 of such diameter as to causetlie rotation at half speed, or once every twenty-four hours, of the attached drum 2'4'. An

y'axially' disposed metallicstrijp 26? is embedded' in the drum 24' of .a dielectric material',A and is posi'- tloned' flush; with the periphery' thereof. Suit- Aal'nly 'mounted upon and insulated 'from a .support 28; disposed inruxtaposition to the drum 24 are three metallic contact fingers or brushes 30,. 32 `and 31 which :resiiientiyv engage the surface of the drum. The foregoing mechanism, constitutes a clock driven timerfor controlling the actuation of the. calendar mechanism, tobenovv described.

Mounted -lrr anyconv-enient manner-and extend- `lng across 'the housing' adjacent to but aboveand 'below the-window' I8', are vguide rollers 36 and 38. ecured tor `opprinite sIdewa'Hsofthe housingare of 40;v I! Yrctataltz'lr supporting,l 'a

' .flo ereceiving'mnn, The

feed roll may be formed of a slender arbor insertable into the center of a roll of material, or if preferred, the interchangeable calender rolls may be provided with an arbor therein, either arrangement being designated at 44. The rolls 44 and 46 are provided with trunnions, detachably received in inclined slots 41 and 48 in the bracket member in a conventional manner. Y A continuous web or sheet of calendar indicia be'aring'material 58 is threaded from the dispensing roll 44, over the guide rolls 36, 38 and thence is secured, in n a manner to be later described, to the receivingI As shown in Figure 2, the relay assembly is housed for convenience as a separate unit in a casing II6, secured to the end of the housing I8 and provides posts of the leads 88, I 82, 82 and |84, the casing |I6 enclosing the solenoid 84, the switch blade 94, dashpot |88, spring 98 and contacts 98, 92.

The operation of the device is as follows:

At some appropriate time, preferably midnight,

'the clock driven timer drum 24 reaches a position in which the switch 26 bridges the three conroll 46. It will be apparent that as roll 46 is rotated, the web 58 will be woundl thereon and withdrawn from the dispensing"1oll 4:4, thereby presenting successive indicia at the display win-"1 dowIB.

Secured in oppositely disposed'br'ackets 52 is a strip member 54 from which extend a plurality of resilient iingers 56, supporting a roller 58 biased thereby into engagement with roll 44. iThe frictional resistance aiTorded by roller 58 constitutes a drag upon the web 58 to take up any slack in the system and insure thereby the proper 'alignment and tautness of the web upon the rolls.

As shown in Figure 9, the receiving roll 46 secures the end 60 of the web 58 by means of a spring clip or finger 62 provided in a recess 54 in the roll periphery. Protruding from one end of the roll 48 is an extension 56 extending outside the housing for the reception of a knob 68, which constitutes a iinger grip for rotating the roll 46 to wind up or advance the calendar web. This feature is especially useful when intentional or inadvertent stoppage of the clock, or other cause necessitates readjustment of the calendar web.

Adjacent one end, the roll 48 isprovided with a gear 18, driven by the gear 12 of an electric motor 14. Gear 18 may be attached to the roll 48 by an overrunning clutch or other conventional slip coupling to permitmanipulation of knob 68 and roll 46 without requiring movement of the gear 12 and motor 14, if desired.

As shown in Figure 8, a pair of positive and ground electric leads 16, 18, from anysuitable power source, are connected to the electric motor of the clock I2. From lead 16, a conductor 88 extends to the contact 32, while lead 18 is connected with a conductor 82 extending to a solenoid 84. A branch lead 86 connects the electric motor 14 to the ground lead 82. Contact 34 is connected by a conductor 88 to a pair of spaced terminals 98, 92. A metallic switch blade 94, pivotedat 98 and spring biased at 98 into engagement with terminal 92, is oscillatably positioned between the terminals 92 in cooperative relation to the solenoid 84, adjustable dashpot |88 of conventional construction being attached to its blade 94 to regulate the time required for spring 98 to move the switch from contact 98 to contact 92- A positive lead I 82 extends from the switch 94 at its pivot 96 to the motor 14.v From the solenoid 84, a lead |84 extends. to a movement limiting switch indicated generally -at 86 and from thence a lead II4 connects with the contact 38. The .switch |06 comprisesa pairof spring contacts |88, II8, between vwhich passes the edge or margin of the calendar .web.9. Contacts |98, III) are connected to leads II4 and |94 respectively andare normally separated by the web 58 except whe-n cut away portions II. of the web pass-therebetween. These portions are disposed -upon the web margin in a ,position correlated to the location of the'lmiter units fora purpose which will be, later apparent;

tacts 38, 32, 34, thus placing the current from leads 88 and 16 in communication with leads 88 and II4. At this time switch |88 prevents enerf. gization o the solenoid 84 by leads I|4 and |84 as will appear hereinafter. Lead 88 therefore energizes terminals 98, 92, and as the switch .diameter to its maximum.

blade 94 is in contact with terminal 92, due to the influence of spring 98, current now flows by lead |82 to motor 14 and thence by leads 86 and 82 to the ground at 18. Activation of the motor 14 now operates roll 46, winding up and advancing the calendar web 58. When the web has advanced nearly to its next desired position, wherein the calendar datum for the next successive day will be presented at window I8, the appropriately placed cut away portion ||2, corresponding to that particular indicia unit, will pass between the limiter switch contacts |88, I IB. This permits the switch |98 to close, and current may now energize the solenoid 84 through leads 18, 88, 82, 25, 38, H4, |86, |84, 84, 82 and 18. This draws the -blade Minto contact with terminal 98 against the action of spring 98, momentarily breaking the circuit to motor 14 from terminal 92 but restoring it through terminal 98. The motor 14 continues to advancethe web 58 until the cut away portion I|2 has passed from under switch |06. At this time the calendar unit will be properly located with reference to the window I8 and the switch |86 is opened, deenergizing solenoid 84. The spring 88 immediately withdraws the blade 94 lfrom terminal 98, deenergizing the motor 14 and stopping further winding ol the calendar web. It should be here noted that dashpot l 8 is designed to permit a slight unretarded initial movement of the switch blade 94 under the influence of spring 98, sufficient to open the circuit through but the dashpot then restricts further movement to such a rate that the blade does not close contact 92 until the clock motor has had suicient time to rotate drum 24 and contact 26 out of engagement with the lingers 38, 32 and 34. The mechanism is now set for its next actuation whereupon the foregoing cycle of operation is prepeated. v

It should be here observed, that at the beginning of the year the dispensing roll will be of maximum diameter, containing for example in one embodiment about 123 feet of paper web, while the receiving or winc'ing roll will be of minimum diameter. As the period of time progresses, the receiving roll will increase in It will be evident therefore, that theweb advancing means must y,turn the roll 48 a diierent amount each actuation in order to advance the web the same amount and present each indicia unit properly before the window. `The foregoing limiter switch responds to predetermined web movement to effect proper mentioned objects of invention, which isoi com;-

pact, attractive appearance, yet will properly indicate the time of day together with correct calendar data, without requiring attention or adjustment for long periods of time.

Further provision is made for changing the calendar rolls to provide data and indicia corresponding to diierent chronological periods.
